The Revolutionary movement for Indian independence' is a part of the Indian independence movement comprising the actions of the underground revolutionary factions. Groups believing in armed revolution against the ruling British fall into this category, as opposed to the generally peaceful civil disobedience movement spearheaded by Mohandas Karamchand Gandhi. The revolutionary groups were mainly concentrated in Bengal, Maharashtra, Bihar, the United Provinces and Punjab. More groups were scattered across India.
Apart from a few stray incidents, the armed rebellion against the British rulers was not organised before the beginning of the 20th century. The revolutionary philosophies and movement made its presence felt during the 1905 Partition of Bengal. Arguably, the initial steps to organise the revolutionaries were taken by Aurobindo Ghosh, his brother Barin Ghosh, Bhupendranath Datta, Lal Bal Pal and Subodh Chandra Mullick when they formed the Jugantar party in April 1906.Jugantar was created as an inner circle of the Anushilan Samiti, which was already present in Bengal mainly as a fitness club.
Established by Pramathanath Mitra it became one of the most organised revolutionary associations, especially in the Eastern Bengal where the Dhaka Anushilan Samiti had several branches and carried out major activities. Jugantar was initially formed by an inner circle of the Kolkata Anushilan Samiti, like the Palmach of Haganah. In the 1920s, the Kolkata faction supported Gandhi in the Non-Cooperation Movement and many of the leaders held high posts in Congress. The Anushilan Samati had over five hundred branches.
